Yeah, I think you're right. It's pretty amazing to me that they'd make the allegation, though, without some pretty good evidence. Apparently the evidence they've got was the statement of some Iraqi officials who were involved. But there's gotta be a paper trail of some kind.
Getting a London or Swiss bank to produce it though might be difficult.
You know what's amazing? Someone not knowing what they're talking about yet making comments based on misinformation.
By design or ignorance is the only question.
